WebbStep-by-step instructions. First, prepare a starch solution. Starch hardly dissolves in cold water, but will grudgingly dissolve in hot water. And while starch may not be overly enthusiastic about dissolving, it is really keen to react with iodine. When it does, it forms a dark blue compound. For this reason, starch can be used to detect iodine. Webbclass, unless you are very certain that they have not been cont aminated. Discard 1oz cups containing starch and use fresh ones each time.
